The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 1998 through June 2008, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and Thomson Reuters’ journal-to-category field definition scheme. Articles tabulated and citation counts to those articles are for the period indicated. Naturally, institutions publishing large numbers of papers have a greater likelihood of collecting more citations than those publishing fewer papers. This ranking is by citations per paper (impact), among those institutions that have collected 25,000 or more citations in space sciences (which here includes astronomy, astrophysics and atmospheric sciences). For papers with multiple institutional addresses, each institution receives full, not fractional, citation credit. Essential Science Indicators lists institutions ranked in the top 1 per cent for a field over a given period, based on total citations. For the current version, 121 institutions are listed in the field of space sciences, meaning that a total of 12,100 institutions were reviewed to obtain these results. Of the 121 institutions, 35 collected 25,000 or more citations. The ranking by citations per paper (impact) seeks to reveal “heavy-hitters” based on per-paper influence, not mere output.
